This study aimed to present a clinical case of orthodontic retreatment in an adult patient with fixed appliance in both arches and extraction of tooth 31, and discuss the limits of the body’s acceptance to orthodontic movements. A 23-year-old patient, coming from a previous orthodontic treatment, attended the clinic of the Professional Specialization School of ABO/MA with a report of pain in the region of the mandibular incisors and aesthetic complaint. The presence of periodontal problem due to excessive buccalization of the mandibular incisors was identified. The orthodontic treatment adopted corrected the excessive buccalization of the mandibular incisors, eliminating the patient’s complaints, and restoring the ideal overjet and overbite, in addition to maintaining bilateral Class I occlusal relationships. It was concluded that, in this case, the extraction of an incisor was an effective alternative for the correction of excessive buccalization of the mandibular incisors.
